Pybytes dashboard not accepting data

I have a WiPY 3 and it was pushing 6 virtual pins to my Pybytes dashboard for several weeks. Now only the first virtual pin gets updated. I experimented with my code and found that if I wait 3 seconds between virtual pin messages, they all make it. If I remove the 3 second pause (or drop it down to 1 second) only the first value makes it. Any ideas why this would happen? It worked fine for several weeks.
